hi all, need some help.

I have a form that has lisview I need to update it every time I go onto the form. I added a method to insert the desired data in the system method OnInitializing, and when the form is loaded for the first time, everything works perfect in worksheet added value, but when I go out with the form, add the values that should appear in the listview, I go to this form, and nothing happens. Added a method to the method onSceneActivatedN, no results. Added logging, when I go again to the form does not work method OnSceneActivated.

How to solve the problem?
